The present research work was performed in 12 Surti buffalo calves with reference to pancreatic juice lipase from birth to early ruminant stage. The pancreatic juice was collected by cannulating the pancreatic duct. The samples were collected 30 min before feeding (BF) and 30 min after feeding (AF) both during morning and evening hours. The results revealed non significant age effect for early neonatal period (first 10 d) but it was found to be significant AF during weekly comparison. Overall lipase activity was found to decline with age but the activity was found to increase with age when expressed for the volume (flow rate) of pancreatic juice secreted during 30 min of time. Diurnal variations, excepting significant higher activity at evening hours at 12 wk, revealed non significant higher lipase level during evening hours (4.53 percent) as compared to morning samplings. Overall, lipase level increased due to feeding was found to the extent of 42.73 percent (3.41 U/ml) as compared to its basal level. Postprandial lipase level at different stages (colostrum feeding, MRP feeding, inclusion of concentrate and hay and inclusion of fodder) revealed significant increase except a decrease recorded on 11 wk. The findings suggested that lipase activity is present at birth and the ontogenic pattern may be modified at birth by the colostrum and milk substitute intake and upon weaning due to modified at birth by the colostrum and milk substitute intake and upon weaning due to development of forestomachs and also due to increase amount of solid food intake
